Fine-grained per-module logging can be configured via the NDN_LOG environment variable. This is especially useful when running unit tests or tools such as nfdc that do not have a configuration file. See ndn-log(7) manual page for syntax and examples.
To run unit tests, NFD needs to be configured and build with unit test support:
./waf configure --with-tests # --debug is also strongly recommended while developing ./waf
The simplest way to run the tests is to launch the compiled binary without any parameters:
# Run core tests ./build/unit-tests-core # Run NFD daemon tests ./build/unit-tests-daemon # Run NFD RIB management tests ./build/unit-tests-rib
The Boost.Test framework is very flexible and allows a number of run-time customization of what tests should be run. For example, it is possible to choose to run only a specific test suite, only a specific test case within a suite, or specific test cases within specific test suites:
# Run only the TCP Face test suite of NFD daemon tests ./build/unit-tests-daemon -t FaceTcp # Run only test case EndToEnd4 from the same test suite ./build/unit-tests-daemon -t FaceTcp/EndToEnd4 # Run Basic test case from all core test suites ./build/unit-tests-core -t */Basic
By default, Boost.Test framework will produce verbose output only when a test case fails. If it is desired to see verbose output (result of each test assertion), add -l all option to ./build/unit-tests command. To see test progress, you can use -l test_suite, or -p to show a progress bar:
# Show report all log messages including the passed test notification ./build/unit-tests-daemon -l all # Show test suite messages ./build/unit-tests-daemon -l test_suite # Show nothing ./build/unit-tests-daemon -l nothing # Show progress bar ./build/unit-tests-core -p
There are many more command line options available, information about which can be obtained either from the command line using the --help switch, or online on the Boost.Test website.
